Description
本發明是有關於一種轉向裝置，特別是指一種兩前輪車輛之轉向裝置。The present invention relates to a steering device, and more particularly to a steering device for two front wheel vehicles.
參閱圖1，現有兩前輪車輛1包括一車架11(為說明方便，圖中車架11的部分以假想線表示)、一樞設於該車架11上之中央桿12、二分別位於該中央桿12兩側的車輪13、二樞設於該中央桿12與該等車輪13之間的連桿14，及多數設置於該等連桿14兩端的球接頭15，該等球接頭15用以連接該中央桿12與該等連桿14之其中一端，及連接該等車輪13與該等連桿14之另一端。Referring to FIG. 1, the two front wheel vehicles 1 include a frame 11 (for convenience of description, a portion of the frame 11 is shown by an imaginary line), and a center pole 12 and two pivotally mounted on the frame 11 are respectively located. The wheels 13 on both sides of the center pole 12, the two links 14 pivoted between the center pole 12 and the wheels 13, and a plurality of ball joints 15 disposed at opposite ends of the links 14, the ball joints 15 The central rod 12 and one end of the links 14 are connected, and the other ends of the wheels 13 and the links 14 are connected.
欲使該兩前輪車輛1轉彎時，藉由騎士轉動該中央桿12而帶動該等連桿14，進而連動該等車輪13轉動達成轉向的功效。然而，該等球接頭15轉動偏擺的範圍較小，造成該等車輪13的轉向角度受到限制而無法進行大角度的轉向，進而連帶影響到該兩前輪車輛1操控性；而且當路面顛簸造成該等車輪13產生Y軸方向的震動時，由於該等球接頭15的轉動偏擺範圍小，使得該等球接頭15需直接承受軸向負載，因而大幅縮短了該等球接頭15的使用壽命。When the two front wheel vehicles 1 are to be turned, the connecting rods 14 are driven by the knight to rotate the center rod 12, thereby interlocking the wheels 13 to achieve the steering effect. However, the range of the yaw of the ball joints 15 is small, causing the steering angle of the wheels 13 to be limited and unable to make a large angle of steering, thereby affecting the handling of the two front wheel vehicles 1 and causing bumps on the road surface. When the wheels 13 generate vibration in the Y-axis direction, since the spherical yokes 15 have a small yaw range, the ball joints 15 are directly subjected to axial loads, thereby greatly shortening the service life of the ball joints 15. .
因此，本發明之目的，即在提供一種便於大角度轉向且使用壽命長的兩前輪車輛之轉向裝置。Accordingly, it is an object of the present invention to provide a steering apparatus for two front wheel vehicles that facilitates wide angle steering and has a long service life.

An axis L1 rotates at a large angle for the axis, and the second steering bracket 63 also rotates at a large angle with the first axis L1 extending in the direction of the first pivoting portion 611 as a shaft center, so that the first steering The bracket 62 and the second steering bracket 63 can have a large angle yaw, so that the wheels 24 can be evenly attached to the upside road surface, especially when the road surface height is too large, thereby preventing the two front wheel vehicles 2 from vibrating. Or shaking, so that the rider has a good sense of comfort, in addition, using the yaw angle absorption The load applied to the steering device 3 prevents the load from directly acting on the cross joint 61, thereby increasing the service life of the steering device 3.
綜上所述，本發明用於兩前輪車輛之轉向裝置3是藉由該第一轉向支架62樞設於該十字接頭61之第一樞轉部611，而該第二轉向支架63樞設於該十字接頭61之第二樞轉部612，且該轉動軸線L’通過該第一樞轉部611之第一軸線L1與該第二樞轉部612之第二軸線L2的交點，該轉向座5以該轉動軸線L’為軸心轉動，同時該第一轉向支架62及該第二轉向支架63沿該第一軸線L1為軸心擺動，進而連動該等車輪24能進行大角度的轉向或壓車。另外，藉由該第一轉向支架62以該第一軸線L1為軸心做大角度的轉動，而該第二轉向支架63亦同時以該第一軸線L1為軸心做大角度的轉動，使該第一轉向支架62及該第二轉向支架63能有大角度的偏擺，進而連動該等車輪24行駛於顛頗路面時能平貼於路面，以避免該兩前輪車輛2震動或搖晃，且利用偏擺角度吸收作用於該轉向裝置3上的負荷，避免負荷直接作用於該十字接頭61上並降低元件間之磨損，進而能增加該轉向裝置3整體的使用壽命，故確實能達成本發明之目的。In summary, the steering device 3 for the two front wheel vehicles is pivotally disposed on the first pivoting portion 611 of the cross joint 61 by the first steering bracket 62, and the second steering bracket 63 is pivoted on the second steering bracket 63. a second pivoting portion 612 of the cross joint 61, and the rotation axis L' passes through the intersection of the first axis L1 of the first pivoting portion 611 and the second axis L2 of the second pivoting portion 612, the steering seat 5 pivoting about the axis of rotation L', and the first steering bracket 62 and the second steering bracket 63 are pivoted along the first axis L1, so that the wheels 24 can be rotated at a large angle or Press the car. In addition, the first steering bracket 62 rotates at a large angle with the first axis L1 as an axis, and the second steering bracket 63 also rotates at a large angle with the first axis L1 as an axis. The first steering bracket 62 and the second steering bracket 63 can have a large angle yaw, so that the wheels 24 can be slid on the road surface when the wheels 24 are driven on the road surface to avoid the two front wheel vehicles 2 vibrating or shaking. Moreover, the load acting on the steering device 3 is absorbed by the yaw angle, and the load is directly applied to the cross joint 61 to reduce the wear between the components, thereby increasing the service life of the steering device 3 as a whole. The purpose of the invention.
